ANTIFREEZING DRINKING FOUNTAIN.

Application led November 12, 1919. Serial No. 337,493.

To all whom it may concern:

Be it known that we, PHILIP MUELLER and ANTON C. SCHUERMANN, citizens ofthe United States, residin at Decatur, in the county of Macon and tateof Illinois, have inventedl new and useful Improvements in AntifreezingDrinking Fountains, of which the following is a specification.

The present invention relates to sanitary drinking fountains and whileit is disclosed in connection with a particular type of bubblerhead,pedal-operated supply fountain, it will be understood that the featuresdisclosed and claimed may be applied to other and various types offountains.

It has for its object to provide -a foun-v tain, in which the drinkingsupply and waste may be ladequately controlled and taken care of, and inwhich sanitary conditions are observed, and, furthermore, provides afountain, which is calculated to withstand low temperatures. withoutdanger of freezing either the supply or waste.

In the drawings herewith is illustrated one embodiment of the inventionand in said drawings Figure 1 is a side view of a fountain made inaccordance with the invention, parts thereof being in section forclearness of illustration,

Figure 2 is a vertical sectional view on an le)nlarged scale of thebowl, pedestal, and

ase,

Figure 3 is a sectional view cock and its connections,

Figure 4 is a view in elevation'of a supply pipe drain,

Figure 5 is a bottom plan view of the pedestal and its anchoring means,

Figure 6 is a view in section of the pin connection between the pedestaland base,

Figure 7 is a detail view to illustrate the pedestal clamping means,

Figure 8 is a view in section of the lower part of a fountain' similarto that shown in Figure 1 illustrating a different type of operatingpedal, y

Figure 9 is a detail view showing the mounting of the pedal lever.

Referring to the drawings by numbers, like numbers indicating like partsin the several views, 10 denotes a base-p1ate, which may be oftheformshown in plan in Fig) of` the supply 5, which base-plate, asindicated in Figs. l and 2, rests upon the curbing of the well or pitinto which portions of the supply and waste depend. The base-plate 10may be secured in any suitable manner, a convenient way of securing it,where conditions are suitable, being the crossbars l1 and the bolts 12,which passl through apertures in the base plate and clamp said bars andbase,- plate tightl to the cover of the well or pit. The" base-p ate isprovided also with locating and holding pins 13 designed to engageapertured lugs 14 on the interior of the pedestal 15.

The said base-plate l0 has a central aperture through which passes thelower section of the waste pipe 16, this being held therein by screw17., the upper end of the wast-e pipe section being threaded in thepresent disclosure and coupled to the upper section of the waste pipe bythe coupling sleeve 18 as shown in Fig. 2. The lower end of the wastepipe 16 will extend into the well or pit to any desired distance and hasat its lower end a coupling chamber 19 for sewer Connection, saidcoupling chamber 19 having preferably formed integral therewith, theradially disposed supply chamber 20,

which connects through the wall of theK chamber 19 with the supply cock21, the inner end of the supply chamber 20 delivering to the supply pipe22, which-risesvertically in the waste pipe 16 t-o the bowl and bubblerhead presently to be described.

The supply cock is coupled with any suitable supply 23 and is providedwith an .automatically closing valve 24, the stem of which passesthrough a stuiiing nut 25 and is connected at its upper end with a link26 upon which is secured adjustably a weight 27 as shown, this weightbeing designed to counterbalance the valve operating parts presently tobe described. The valve 24 is preferably provided With a clos- -ingspring 28 (see Fig. 3) sothat when released the valve will, by thespring and weight, automatically close. Mounted in the cock body on theother side ofthe valve seat is a stop and regulator 29 by .means 'ofwhich the ow may be regulated or entirely cut off if desired, asindicated in Fig.' 3.

In order that the supply pipe 22, which will, of course, befllled withwater upon cates with the outlet sideof the cock and has therein aspringclosed valve 31, the stem l33 of which valve may be eccentricallyplaced or otherwise formed so as to give free water passage past thevalve. The spring 32 surrounding the valvestem bears against a flange onsaid stem and normally tends to close thevalve. The upper end of thevalve stem 33 passes through asuitable stulling nut 34 and said stem isactuated by a finger 35 projecting from the coupling head 36, whichlconnects the stem of the valve 24 with the link 26. Vith thisarrangement it will be seen that when the valve 24 is opened, the finger35 will be raised, releasing the stern 33 and the valve 31, which valvewill be immediately closed by its spring and the water will pass to thesupply chamber 20 and the supply pipe 22. When the valve 24 is closedthe linger 35 willforce the stern 33 and valve 31 downwardly against thespring 32 opening the valve and permitting the water to drain into thechamber 30, from which lchamber it passes by the drain pipe 37 to thecoupling chamber 19 of the waste pipe, the drain connection 37 beingbent as shown in Fig. 3 to form a water seal.

If desired, the drain pipe 37 for the cock can be led directly to thesewer trap as shown in Fig. 4.

With this -arrangement the supply pipe 22 is drained at its lowestpoint, no water being left standing therein, and as the water passesthrough the drain cock in the manner described, it will, of course,create a .vacuum through the entire length of the supply pipe 22 anddraw in fresh air, thus aerating the pipe at each operation of fillingand draining, which tends to create and preserve a highly sanitarycondition of the supply pipe.

The link 26 is adjustably connected at its upper end with the' pedallever 38, which pedal lever is hung from depending lugs 39 on theunderside ofthe base plate, the lever, for compactness, being preferablyarranged as shown, surrounding the waste pipe 16 with its opposite endcurved upwardly and passing through an aperture 40 in the base plate,

a foot pe al 41 being pinned or secured in any suitab e manner to theupwardly curved end of the lever 38. Preferably the baseplate will beprovided with depending guiding lugs 42 to control and guide themovements of the lever 38 and prevent any side movements thereto. Thepedal 41 projects outwardly through a narrow slot 43 in the Wall of thepedestal at thebase 44 of the pedestal, into the pedestal crescent sothat it may be readily manipulated by the foot. With this arrangement itwill be seen that when the pedal 41A is depressed, the lever 38 vmeans(not shown).

'mit the supply valve to close and open the waste for draining.

The upper section of the waste pipe 16 is provided with a cap nut 45,which is recessed at its upper end to form a gasketreceiving groove inwhich a suitable gasket 46 is placed, and provides a slip joint unionwith the bowl waste 47, the lower end of which bowl waste is tapered sothat it may be slipped into -the cap nut and past the gasket readily,and when brought to position will form a water and gas tight slip joint.The bowl-waste 47 is secured to the bowl by the screws 48,1which passthrough the bowl 49 and engage the head of the bowl waste 47, a packing50 being interposed between the headA of the bowl waste and the bottomof the bowl as shown in Fig. 2. Said screws 48 serve also to fasten thestrainer 51 in place, which strainer comprises any suitable gratedportion and a central sleeve 52 rising to a considerable distance abovethe bottom of the bowl and surrounding the supply pipe.

becured to the underside of the bowl waste head is a packing, which, asshown, com prises a gasket 53 of any suitable material and which is heldby the annular ring 54 and suitable holding screws, this packingengaging the upperlend of a sleeve 55 which surrounds the waste pipe, asbest shown in Fig. 2, said sleeve at its lower end being threaded into aboss 56 on the base-plate 10 so as to be firmly anchored thereto. Whenthe bowl 49 with its attached waste pipe and the packing just describedis dropped into place, the packing 53 will effectually seal the upperend of the pipe and a dead air chamber is thus formed by the pipe 55,surrounding the waste pipe audits contained supply pipe, and surroundingthis dead air chamber will be the pedestal 15 with its relatively largeand practically closed air chamber.

The bowl 49 not only rests upon and seals effectually the pipe 55, butit rests also on the upper part of the pedestal 15 as shown and may besecured there/to by any suitable In order to lock the pedestal and itsassociated parts in place, it is preferably, after being located on thepins 13 in the base-plate, secured by means of a clamping pla-te 57surrounding the pipe 55 and bearing against lugs 58 on the inner wall ofthe pedestal. The said clamping plate 57 is forced downwardly to clampthe pedestal firmly in position by means of screws 59 passing through aplate 60, which plate bears againstpins or lugs 61 projecting outwardlyfrom the pipe 55. l'For convenienc'e in assembling,ithe plate 60, whichis apertured to slip over the pipe 55, is provided with radial slots 62,which will pass over the ins 61, and the plate 60 canthen be rotate soas to carry the slots out of line and give a bearing for the plateagainst lthe pins when the screws are set up. From the foregoing it willbe seen that, upon adjusting the plates within the pedestal and aboutthe dead air chamber pipe and then setting up the screws 59 the pedestaland the parts carried thereby will be firmly clamped, and furthermore,that the arrangenmet is such that by simply removing the bowl 49 theparts are readily accessible for dismantling and taking down thefountain.

The supply pipe 22 extends 'upwardly into the bowl waste and is therecoupled with the bubbler head pipe 63 which in turn carries any suitablebubbling head 64.

From the foregoing itis clear that a drinking fountain is provided inwhich the supply and waste are so disposed that danger of freezingisvreliminated; in which the supply is protected from contamination;which may be readily assembled and taken down for inspection and repair;and lin which automatic flow and drainoccurs on manipulation of thesupply-valve operating devices.

In the construction shown in Figures 8 and 9, we have illustrated aslightly dili'erent form of pedal lever and valve operating mechanism.

Instead of the lever arrangement shown in Figures 1 and 2, we providethe bell v without departing from the lspirit of the incrank leverhaving the foot pedal 66, said lever 65 being mounted in standards orsupports 67 b-y means of the pivot pin 68. The upper end of the lever 65is pivotally connected with a valve operating rod 69 which dependsthrough the opening in the curbing and is connected pivotally with thecoupling head 36 of the Ysupply valve 21 and preferably, the said supplyvalve 21 will be arranged on the side -of the cham.- ber 19 voppositefrom that'shown in Figures 1, 3 and 4 in order that the coupling rod 69may descend directly to the valve and be connected with the head 36.

By this arrangement, we are enabled to dispense with the weightedconnecting link with 'which the otherform of the inven-l tion isprovided, the normal weight of the connectmg rod: 69 being suicient .toovercome the weight of the pedal lever 65 and maintain the parts in thenormal full line position shown, with the pedal lever raised and thesupply valve closed.
